Elephant S.O.S..doc

1、1Elephant S.O.S.In the Xishuangbanna Dai Autono- mous Prefecture is the Xishuangbanna National Nature Reserve in southern Yunnan Province. Despite its relatively limited area of less than 250，000 hectares， the reserve is home to one quarter of Chinas wild animal species and a fifth of its wild plant

2、 species. The nature reserve is warm， humid and rainy all year round， gifting the area tremendous biodiversity and Chinas best-preserved tropical rainforest at a comparatively high latitude and altitude. An abundance of rare animals inhabits the tropical rainforest， of which the wild Asian elephant

3、is the most famous species. The flagship animal even won Xishuangbanna the reputation of being the “elephant prefecture” in ancient China. Today， the worlds two major species of elephants are distinguished by their native continents： Asia and Africa. With an estimated wild population of between 30，0

4、00 and 50，000， the Asian elephant is distributed across 13 Asian countries， including China. Statistics show that about 300 wild Asian elephants lived in China in 2015， of which 250 were located in Xishuangbanna. Wild Elephant Valley， one specific scenic spot in 2Xishuangbanna National Nature Reserv

5、e， is home to about 70. Observation and Protection On an ordinary day in July 2016， it was stiflingly hot despite the towering trees shielding people from the suns direct rays. The light still filtered through the dense branches and leaves. “Keep silent， ” whispered Yan Hanlu， head of the Asian Obse

6、rvation and Protec- tion Center. “Dont make a sound.” Yan then pointed towards a group of wild Asian elephants relaxing and drinking from a river just 20 meters away. He quickly scribbled a note reading， “At 11：30 a.m.， 26 wild Asian elephants were spotted： one adult male， five adolescent males， fou

7、r calves， ten adult females and six adolescent females.” He was so thrilled to see such a large group that his writing was especially illegible. Wild Elephant Valley， located in the Mengyangzi section of the Xishuangbanna National Nature Reserve， first launched efforts to protect the wild Asian elep

8、hant in the late 1980s. Then， governmental agencies began placing salt at river banks the elephants frequented. Wild elephants need salt and other minerals that are often hard to come by in their natural 3environment. In 1991， the Xishuangbanna Nature Conservation Bureau created observation posts in

9、 Wild Elephant Valley to conduct scientific observations. Later， when the valley became a forest park for wild elephant viewing， breeding and research， many agencies involved in elephant protection moved into the valley. The Asian Elephant Observation and Protection Center， established in June 2005，

10、 is one of them. Yan Hanlu and his coworkers regular routine includes tracking and monitoring wild elephant herds as well as issuing alerts and warning tourists. “Many tourists want to get as close as possible to the elephants， ”Yan remarks. “We are not only responsible for their safety， but also fo

11、r preserving the elephants domain. No viewing should disturb the elephants everyday lives.” Reproduction and Rescue Alongside the Asian Elephant Observation and Protection Center， the Asian Elephant Breeding and Rescue Center is also based in the valley. Bao Mingwei， a veterinarian at the breeding a

12、nd rescue center， is known for his skill at delivering anesthetics by blowing them through a pipe. Using his long blowpipe， he can sedate a wild Asian elephant from ten meters away so 4specialists can treat and help it. In 2007， Bao and his coworkers found a sick adult female Asian elephant in the w

13、ild， which they named Ping Ping. She had contracted a severe infection around her hip and was nearing death. Wary of attack by members of her herd， Bao and his colleagues sedated Ping Ping with the pipe- blown anesthetic and immediately treated her on-site. Within two weeks， Bao and other experts ha

14、d formulated a treatment plan and successfully performed surgery. Along with rescuing wounded wild elephants， the breeding and rescue center also rehabilitated four elephants that had been used to smuggle drugs. They were seized by Chinas border control. “Foreign drug dealers fed these poor things d

15、rugs in the hope of concealing and trafficking them， ” explained a representative of the breeding and rescue center. “The four elephants were sent to Hainan Province for rehabilitation before being returned to Xishuangbanna.” During their stay at the center， workers walked the four elephants through

16、 the forests to search for food every day， along with other elephants. “We couldnt just lock them up， ”adds Bao. “They need more supervised time in their natural environment before they are ready to survive in the wild.” Long Road Ahead 5Asian elephants face the same persistent threats they have fac

17、ed for years worldwide： human development and the ivory trade. Human development steadily encroaches on elephant habitat， pushing them out. Compounding the problem， the gradual shrinking of tropical rainforests has further exacerbated habitat loss， forcing elephants to venture out of forests in sear

18、ch of food， into areas inhabited by humans. Despite international efforts to end it， the ivory trade remains rampant globally， and as well as causing a serious gender imbalance， it has even influenced the animals genetics. In a reversal of Darwins “survival of the fittest， ” adult male elephants wit

19、h the most beautiful tusks have the hardest time surviving. Since adult males with small or even absent tusks survive more easily， the dominant tusk gene is gradually disappearing. At present， this external pressure has resulted in an absence of the iconic incisors in at least half of the global mal

20、e Asian elephant population. And the male-female ratio of Asian elephants worldwide sits at a staggering 1：12. Asian elephants have approximately the same life expectancy as humans and stop growing at about age 30. Also like humans， 6females usually give birth to only a single offspring per pregnanc

21、y and reach sexual maturity in their teen years. This long life cycle makes threats to the species population even more challenging to face. For years， the Xishuangbanna National Nature Reserve has been making tremendous efforts to preserve wild Asian elephants. To reduce human-elephant conflict， th

22、e nature reserve has reduced traditional rubber plantations through developing commercial agarwood forests， and launched projects such as biological isolation belts and elephant food bases. Moreover， a comprehensive observation network for wild Asian elephants has been established. More than 40 obse

23、rvation spots have been set up across the nature reserve， where professionals identify and track individual elephants and collect data. Complementing strict international bans on the ivory trade， the nature reserve has carried out extensive international cooperation in recent years. Large areas for elephant protection have been designated along border areas. By 2015， China and Laos had jointly designated five zones for joint elephant protection with a total area of 200，000 hectares.
